Sorry but may I ask whats different with torco and race fuel I thought torco was race fuel
Sorry but may I ask whats different with torco and race fuel I thought torco was race fuel
Sorry to everyone for the long delay...im in military and i finally got back home to DYNO my cobra...first off here is the list of mods then the numbers...
stock motor
2.9 whipple
W/ stock 3.5 pulley produced 19lbs of boost (dynoed car with 3.5)
W/ 3.25 pulley produced 22.5lbs of boost (i was not expecting to see 22.5lbs w/ this pulley so i throw the 3.5 back on...ill be back in the shop w/ 3.25 when i pick up my race gas)
Billet flow 4 piece W/ idler set
80lbs injectors
GT dual fuel pumps
FPDM dual pump re-wire kit
Fore fuel hat
JLT RAI intake
SCT 2400 maf
billet flow throttle body
stock headers
Pypes violator X-pipe with out cat's
Pypes violator cat-back
EGR delet kit
SCT tuner
18 timing
11.8 a/f
630whp/595tq:burnout:
Thank you so much for that info. What pump gas do you use? 91/93 also what elevation are you at? what city/state was it dyno'd in?
It appears your 2.9 was worth about 30 more rwhp that most 2.3 numbers I see posted.
The 2.9, like the KB 2.8, has more potential as it can make displace a larger amount of air at a given rpm, whereas you can't spin the smaller blowers fast enough to create that kind of airflow. On 15-18psi, most blowers will make around the same numbers. When you get into the 20's that's when the differences in sizes start to show. Not that it would be efficient, but just to give you an idea, a 2.2 KB or a 2.3 Whipple won't be able to produce enough airflow to create more than say 25psi, but a 2.9 Whipple or 2.8 KB could probably flow enough air at max rpm to create maybe 30psi. Like I said, obviously that's not recommended, just giving you an idea that's it's more about flow potential.Not to be a party crasher but shops around here won't tune 93 above 18lbs, and I have had a friends car making 18.8 on a 2.6 KB make 635/569, so the next question pricewise is how does this stack up to a 2.8 since a 2.6 is actually cheaper than a 2.9?

Okay know that I've looked up torco and read about it above, can I tune on pump gas while at dyno then just add this and turn boost up to 22 with the 3.25, please let me know guys, my suspesicion is u need to drive the car to mix it what's your thoughts??
Thanks

OK if the KB 2.6 is on par with the Whipple 2.9 and the KB 2.2 is on par with the Whipple 2.3 then I have a few questions.
What makes KB owners choose a 2.6 over a 2.2? Surely there's some characteristics of the 2.2 that make it more desirable to some people or they wouldn't buy them right? They'd just get the 2.6 and make more power.
With that said would those same desirable characteristics make the 2.3 a better option for some over the 2.9?
Also to D3 Racing, your buddy making 635 on a 2.6, was that pump gas? 91/93? what other power mods to motor to do that?
Thanks

Well crap....I guess I'll be putting the 3.50 pulley back on today and swapping belts back....again. There's no way I want 22.5 psi on a stock motor....I'm a little leary of 19psi with the 3.50 pulley honestly.....
60lb Injectors
4# Lower Pulley
Kenne Bell BAP
12" K&N
4" CAI
Accufab Throttle Body
SLP Longtubes
Flowmaster Catback
AFCO Dual-Pass Heat Exchanger
20* Timing, 18.8 psi
93 Octane w/ TORCO
HP: 635 TQ: 569
He posts on here as well, sold that car to go to a 3.4
Would 100 octane be safe on 22 psi?
Well the main reason people choose a 2.6 or 2.8 over a 2.2 is the 2.2 is no longer made, so you can’t buy it new. Finding a good used one is harder to do. The 2.2 is definitely a stout blower that a lot of people love, it really shines right in the range for pump gas(16-18psi). Then there’s the whine, the 2.2 KB almost can’t be matched in blower whine. The 2.6/2.8 definitely has more potential and will make more power per pound of boost above 19psi though.OK if the KB 2.6 is on par with the Whipple 2.9 and the KB 2.2 is on par with the Whipple 2.3 then I have a few questions.
